Must watch Parrot Spectacle Part3

Psittaciform diversity in South America and Australasia suggests that the order may have evolved in Gondwanaland, centred in Australasia.[8] The scarcity of parrots in the fossil record, however, presents difficulties in confirming the hypothesis.

A single 15 mm (0.6 in) fragment from a large lower bill (UCMP 143274), found in deposits from the Lance Creek Formation in Niobrara County, Wyoming, had been thought to be the oldest parrot fossil and is presumed to have originated from the Late Cretaceous period, which makes it about 70 million years ago (Mya).[9] Other studies suggest that this fossil is not from a bird, but from a caenagnathid theropod or a non-avian dinosaur with a birdlike beak.
